Membrane filtration of wastewater from gas and oil production

Abstract

More than 88 billion barrels of wastewater are produced yearly in the world from gas and oil production. Given the rising demand for drinkable water, there is a need for advanced purification processes. Here we review membrane filtration processes used in the gas and oil production for wastewater treatment, with focus on microfiltration, nanofiltration, ultrafiltration, reverse osmosis, forward osmosis, membrane distillation, and electrodialysis.
